にされている。An example thereof will be described with reference to the drawings. In FIG. 4, 1 is a tundish, 2 is an orifice plate, and 3 is a cooling mold. The molten metal 4 enters the cooling mold 3 through the orifice plate 2, is cooled by the cooling water discharged from the cooling water nozzle 7 through the cooling water introduction port 5 through the cooling water passage 6, and forms the ingot 8. The ingot 8 has its surface cooled by a wiper 10 attached to the tip of a support 9 attached to the cooling mold 3, and is secondarily cooled by a secondary cooling nozzle 11 through an air cooling section. The secondary cooling nozzle 11 is of a split type as shown in FIG. 5, and the heat insulating material wall 12 is provided on both sides of the ingot 8.
The bracket 12 'is fixed to the vehicle so that it can be moved forward and backward.

Since the secondary cooling nozzles 11 are separately installed on both sides of the ingot 8, it is difficult to align them with the center of the ingot 8, and if so, non-uniform cooling will result.
Also, the slide must be done separately from both sides of the ingot, so you need two people at the same time, or if you have only one person, work on one side and then turn to the other side. Not only that, it can be both troublesome and dangerous.
そこで本考案では、これらの問題点を一挙に解決せんと

リットとしてもよい。FIG. 1 shows an example thereof, and the same parts as those in the conventional example have the same names and the same reference numerals. Reference numeral 13 is a supporting rod fixed to the heat insulating material wall 12 and slidably holds the holder 14. Each holder 14 can be fixed at an appropriate position by a stop curler 15. As is clear from FIGS. 2 and 3, a worm 16 is rotatably attached to the holder 14 by a handle or a motor, and the worm 16 is directly attached to the worm gears 17 and 17 fitted into the supporting rod 13. In addition, it meshes indirectly. An arm 18 is hung below the worm gear 17, and a cooling water pipe 19 is fixed to the lower part of the worm gear 17. A wiper 20 is attached to the tundish 1 side of each cooling water pipe 19, and a secondary side is provided on the surface opposite to the tundish 1. A cooling water nozzle 21 is arranged. The wiper 20 is a semi-circular one having an inner edge that is concentric with the generated ingot 8 and has a diameter smaller than the ingot diameter, and the inner edge is in sliding contact with the surface of the ingot 8. A plurality of secondary cooling water nozzles may be provided at regular intervals, or may be a single slit.
